The Fourth Element Xerotherm Top is the ultimate base layer for drysuit diving, engineered to keep you warm, dry, and comfortable underwater. Made with NASA-developed Polartec® Powerstretch®, it traps a layer of air next to the skin, providing superior insulation and moisture management. The long body and flat seams prevent separation from leggings, while thumb loops keep sleeves in place during donning. With ultra-fast wicking properties, the Xerotherm top efficiently draws moisture away from the skin, maintaining a thin, insulating air layer for extended comfort. Perfect for wearing alone under a drysuit or layered with other undersuits for maximum thermal performance.
